If you drop a ball-bearing and a cannon ball out of an airplane they will both fall at the same rate of acceleration, which means the mass of the body in free fall does not determine the rate of acceleration.
Interesting situation, so what exactly determines the rate of gravitational acceleration?
It might be helpful to realize that gravity itself is not a force of any kind, as gravity is a dynamic response to the condition of field and or the environment in which free fall occurs.
If we accept gravity to be an effect of an underlying force of energy accelerating symmetrically to the center of the earth we just might start to understand why free fall occurs and why the rate of acceleration is the same regardless of the mass of the body falling.
Gravity control is as much about coming down as it is about going up, so if we can grasp the reason why free fall occurs we are half way there in understanding how to achieve gravity control.
Every mass has an energy component just as the planet earth has an energy component and it is this underlying force of energy which determines gravitational acceleration.
On top of this every mass has both internal dynamics and external dynamics, an inside and an outside, whereby the internal and external dynamics remain balanced in order to allow a body of mass to remain structurally stable.
During free fall the falling mass must suffer a decrease in energy relative to the field in which it is falling at a rate proportional to gravitational acceleration.ย If the falling mass did not suffer a decrease in energy relative to the field in which it is situated it would not fall.
In fact if it were possible to increase the underlying energy of a mass relative to the field in which it is located not only would it not fall but it would in fact rise skyward.
A simple example of this is a hydrogen balloon, as hydrogen has the highest ratio of energy per unit of mass of any known element, (in relation to the underlying force of energy inherent to all physical structure).ย ย Therefore the reason why hydrogen rises is because of its high energy component.
And yes hydrogen is lighter than the surrounding air, but this is not exactly the whole story.
If we refuse to acknowledge an underlying force of energy determining the form and function of all physical structure we are not going to get very far in respect to gravity control.
